Cisco Ssh 1.25 - [best]

Cisco SSH Version 1.25 represents an early implementation of the Secure Shell (SSH) protocol, developed for Cisco IOS devices in the late 1990s. This version was built on top of SSH-1 (specifically SSH Protocol Version 1.5), which was originally designed by Tatu Ylönen. At the time, it replaced insecure remote management protocols like Telnet and Rlogin by providing rudimentary encryption and authentication.
